ginnis on capitol hill where lawmakers grilled health and human services secretary kathleen sebelius over the problem. ,,,,,,,, over the next 40 years the united states population is going to grow by over 90 million people, and almost all that growth is going to be in cities. what's the healthiest and best way for them to grow so that they really become cauldrons of prosperity and cities of opportunity? what we have found is that if that family is moved into safe, clean affordable housing, places that have access to great school systems, access to jobs and multiple transportation modes then the neighborhood begins to thrive and then really really take off. the oxygen of community redevelopment is financing. and all this rebuilding that happened could not have happened without organizations like citi. citi has formed a partnership with our company so that we can take all the lessons from the revitalization of urban america to other cities. so we are now working in chicago and in washington, dc and newark. it's amazing how important safe, affordable housing is to the future of our society.
